ClickHouse

Run read-only SQL against your ClickHouse over its HTTPS interface.

Connect a ClickHouse deployment's HTTPS interface to run read-only SELECT/SHOW/DESCRIBE queries with server-side row caps.

Connect

Credential field	Required	Where it comes from
Password (PASSWORD)	Yes	The database user's password.

Setting	Required	What it is
Host URL (HOST_URL)	Yes	The HTTPS interface, e.g. https://abc.clickhouse.cloud:8443.
Username (USERNAME)	No	Database user. Defaults to default.

Tools

Tool	Access	What it does
Query (yekar.clickhouse.query)	Read	Run one read-only SQL statement against the connected ClickHouse and return JSON rows, capped server-side.
List tables (yekar.clickhouse.list-tables)	Read	List the tables visible to this connection, per database.

Notes

• Point the Host URL at the HTTPS interface - ClickHouse Cloud exposes it at port 8443 by default.
• Use a read-only database user; the surface refuses non-read statements regardless.
